Answer 2

Sum of two rational no. = 17/4

One rational no. = 5/2

So, Let the other rational no. be "x".

Therefore,

\begin{gathered} = > \frac{5}{2} + x = \frac{17}{4} \\ \\ = > x = \frac{17}{4} - \frac{5}{2} \\ \\ = > x = \frac{17 - 10}{4} \\ \\ = > x = \frac{7}{4} \end{gathered}=>25+x=417=>x=417−25=>x=417−10=>x=47
